The Effect of River-Ice Break-Up on Suspended Sediment and Select Trace-Element Fluxes
River-Ice Break-Up Suspended Sediment Trace-Element Fluxes
2009/10/26
Ice break-up on northern rivers presents a unique research challenge because of
its dynamic nature and complexity of physical, chemical and biological processes.
Rapidly moving ice, ice jamming, flo...
Sediment Fabric and Anisotropy of Hydraulic Conductivity in Sandy Till,Wisconsin, U.S.A.
Sediment Fabric Anisotropy of Hydraulic Conductivity
2009/10/23
The orientation of macroscopic and n~icroscopic particles in silty, sandy basal
till appears to have little effect on aquifer anisotropy. The orientation of 108
elongate pebble and cobble-sized part...
A Simple Automatic Calibration Routine for the HBV Model
Automatic Calibration Routine HBV Model
2009/10/23
A simple, but efficient, method for automatic calibration of the conceptual HBV
rainfall-runoff model was developed. A new criterion, which combines the com-
monly used efficiency criterion R 2 and ...
A Model for Water Exchange Between the Baltic Sea and the Gulf of Riga
Water Exchange Baltic Sea Gulf of Riga
2009/10/23
A model for water exchange of a basin connected to the open sea by two channels
has been worked out. The model is applied on the Gulf of Riga, where the
water exchange processes versus strong landba...
Estimation of Parameter Uncertainty in the HBV Model
Estimation of Parameter Uncertainty HBV Model
2009/10/23
Usually the HBV model is calibrated by seeking one optimal parameter set that
represents the catchment. From experience we know, however, that it is hardly
poss~ble to find an unique parameter set. ...
Priestley-Taylor Evapotranspiration in HBV-Simulations
Priestley-Taylor Evapotranspiration HBV-Simulations
2009/10/23
Estimations of potential evapotranspiration as input to runoff calculations with
the HBV model are usually given as monthly standard values calculated with the
Penman method. Daily changes in the we...
Nutrient Exports from Two Agriculture-Dominated Watersheds in Southern Sweden
Nutrient Exports Two Agriculture-Dominated Watersheds Southern Sweden
2009/10/23
Nutrient concentrations and exports were monitored for eight years in two agriculture-
dominated watersheds in the central part of the Vastgota Plain in Sweden.
The hydrology and the nutrient concen...
Changes of Ionic and Oxygen Isotopic Composition of the Snowpack at the Glacier Austre Okstindbreen,Norway,1995
Oxygen Isotopic Composition Snowpack Glacier Austre Okstindbreen
2009/10/23
Marked vertical variations of ions and oxygen isotopes were present in the
snowpack at the glacier Austre Okstindbreen during the pre-melting phase in
1995 at sites between 825 m and 1,470 m above s...
Animal Communities in Icelandic Rivers in Relation to Catchment Characteristics and Water Chemistry
Animal Communities Icelandic Rivers Catchment Characteristics Water Chemistry
2009/10/23
Catchment areas of Icelandic rivers are mostly barren or with little vegetation
cover in the highlands, but with heathland and mire vegetation in the lowlands.
Chemical composition and nutrient avai...
Observations of Ice and Its Sediments on the Baltic Sea Coast
Observations of Ice Sediments Baltic Sea Coast
2009/10/23
Ice samples were taken in winter 1996 for determining the quality and quantity
of sediment inclusions (suspended matter). The study area was the coast of the
Gulf of Finland in the Baltic Sea. The d...
Snowpack Chemistry During Snow Accumulation and Melt in Mature Subalpine Forest and Regenerating Clear-Cut in the Southern Interior of B.C.
Snowpack Chemistry Snow Accumulation Mature Subalpine Forest
2009/10/23
Chemical profiles in snowpacks were observed during snow accumulation and
melt periods at subalpine sites in the southern interior of British Columbia. During
accumulation periods, concentrations of...
Sediment Bound Contaminants in a Remote Northern Delta
Sediment Bound Contaminants Remote Northern Delta
2009/10/23
Deltas of major rivers are among the most productive and environmentally sensitive
components of riverine systems in cold regions, and are of great hydrological
and ecological importance. Much of th...

Long-term Variation Meromictic Lake Nordbytjernet Groundwater Fluctuations
2009/10/23
A zone with permanent anoxic conditions prevailed in the deep waters of Nordbytjernet
before 1978 due to a significant depth gradient in dissolved substances.
High concentrations of manganese and bi...
